larly te carriage return devices in type-` writers.

The object of my invention .is to provide a device by means cf which., the carriage .my be quickly and easily returned to initial position, that is, in pcsition to start a new line Without raising,r the hand above tbe keyboard, cui by a single lateral movement thereof.

A. further object, is to provide a device which will be strong, durable, of low cost to manufacture, and one which will not readily get eut of crder.

A. still further object, is te provide e, de vice which may be easily attached to any typewriter.

@ther cbg'ects will appear hereinafter'.

My invention censists generally in an oscillatory shaft, at one end of which is an upvverdly extending arm adapted to be ectuated by tbe operator ef the machine, and at 4the other end of the shaft, a segmental gear, 'which in combination with a pinion, drum, and flexible tape, draws back the carriage, tbe arm being arranged at one sicle and adjacent to the keyboard.

My invention will be more readily under stood by reference to the accompanying drawings, forming a part cf this' specification, and in which,

Figure l a side elevation oi typewriter equipped with a device embodying;

my invention, in its preferred form, Fig. 2 is an end elevation ef the same, and Fig. 3 is en enel elevation of a typewriter equipped with a device embodying my invention in e m dified 'foi-ni.

Referring now to the drawings, especially te Figs. l and il, i is e shaft mounted in the bearings on the righi-band sifie of the fraine of the typewriter. Upon the fon Ward end oi the shaft l, is an upwardly extending handle er lever, which is of a suitable lengt-ii. its shown in the drawings, the sliat is bent upwardly as at 4, forming tbe handle or lever 5.

Un the other end of the shaft l is bras-esi, or otherwise secured, the segn'iental gear l',

Suitably mounted' en a stud shaft 8 ixed te ille frame il, is a drum l0. Riveted or ell'lerwise secured to the elruni l0, as at 1i, is a flexible tape lil. The tape l2 is pariially Wound about 'elle drum, and extends upwardly and passes over' s. roller i3, the shaft. lli ci' ivliicl1,is suitably secured to the frame Il. is shown in Fig. 2 of tbe drewings, it is secured te tbe top of the frame by the screw l5. llie'tape l2 then extends to the opposite end of the machine, Where it is suitably secured es at 16 te tbe carriage l?.

lotaably lineal on tbe .elicit-8 isn pinion i8 which meshes with the segmental gear 7. The latter ere of .such proportion that a quarter turn of the segment Y, or obviously of the handle 5, 'will cause a complete roteu tion of the pinion 18 and consequently the drum 10.

The form of my device just described (Figs, l and 2) is to be manufactured or assemblecl simultaneously with the rest of the machine, and the franse will have t be shaped when cast, to accommodate the device.

As shown in the dreivings (Figs. l and 2), the frame 3 is recessecl as at 19 to receive the drum l() and the segmental gear 'l'. The shaft l is secured to the frame 3 in a borizontal position. When the carriage of the niacliine is in initial position, the handle or lever is down, but as the carriage moves to the left, it gradually rises, until the carriage is at the limit ci' its movement When the l1analle is in a lvertical position. New the operator by a right lateral nievement of the band, gives the handle a quarter turn downwardly, that is te a horizontal position. This oscillates tbe shaft, which in turn through the medium ci" the segment 'i' and pinion 18, revolves the ruin l0. The drum draws the .tape with it, and the tape being secured to the carriage, pulls it tc the right, thus re turning' the carriage to its normal position. lt is obvious that this form of my device is not adapted to be attached. to machine which is already in use, as it Wonldbe teo expensive, and in some cases impassible to recess the frame se es to receive 11i' ev,Y

To facilitate placing the device on n ina-A cbine already in use, l so construct the deice as to constitute an attachment. This form is shown in Fig. 3 of the drawings. As shown therein, the main parts of the device remain the same, die dilfei'eiice being in the support. This is formeel of a, stout metal band 0i' casting 20, which igoeni, oi' Cast to Coufoi'm to the shape of that portion of die frame lo which it is to be aimfaelied, and is secured *.'o it by the sciewf; Q1. It is obvious that for euch eepii'a'e make, this auxiliary :frame will have to be oi ai slightly different slmpo so as to il'iou'oi'u'i to the particular shape of the .l'i'ziuie oi" lie typewriter. In the iiti'zieluneii'. :form shown iii Fig. 3, the shaft l, is suitably mounted at its ieai' end in bem'- ings 22 and Q3 iu ille auxiliary frame 20 instead of iii the reni bracket 2 as Shown in Fig. 2, the drum und pinion Shzit 8 also oeing suitably mounted :is at 24 in che frame 2O above ille shaft l. The roller shaft linstead of being mounted on the fi'aine 3 as in Figs. l :and 2, lies bearings iu the frame 20. lllius fill pzi'i'ls of my device are mounted in the auxiliary frame 2O forming a. lcom plete utuelmieiii; 'which ,may be readily secured to illie frame of the uypewiiteiz Hin/'ing described my inveiitioiiwha's claim as new, and desire to secure by Leiters Patent, is

A typewriter liuvixig the ordinary eariiage and frame, in combination with an oscillaory shaft mounied upon the side of Said iframe, an upwardly exeiiding lever upon the forwardv end of said shaft, said level' be ing` arranged :it one sicle of anni afijaeen 'bo the key boei-il azul adapted to be swung olitment m. the henri of the operator to oseiliate zuid elmfit-7 zi segmental gear fixed io one end of said slk-ifi, n, di'uim rotatably mounted acijnceu to said segmental geni', a pinion ixed to said drum and meshing with said gear und n iexible tape secured :it one end 'izo saioi drum and ai the other end to said carriage, substantially as described.

In iestimony whereof I have signed my name to @his specification in he presence of 'two subscribing Witnesses.
